Spence Children’s Anxiety Scale – Parent (SCAS-Parent)

Description
The scale is completed by a parent of an anxious child between the ages of 6 to 18. It provides an overall measure of anxiety together with scores on six sub-scales each tapping a specific aspect of child anxiety.

Validity
The scales was normed and validated by Nauta, Scholing, Rapee, Abbott, Spence and Waters (2004) with 484 parents of anxiety disordered children and 261 parents in a normal control group. Results of confirmatory factor analysis provided support for six intercorrelated factors, that corresponded with the child self-report as well as with the classification of anxiety disorders by DSM-IV (namely separation anxiety, generalized anxiety, social phobia,
panic/agoraphobia, obsessive–compulsive disorder, and fear of physical injuries). Compared to the child version of the same test, parent–child agreement ranged from 0.41 to 0.66 in the anxiety-disordered group, and from 0.23 to 0.60 in the control group.

Interpretation
Scores consist of a total raw score (between 0 and 114) and six subscale scores. Results are also converted to percentile ranks based on an Anxiety Disordered Children sample and a Normal Population Children sample, based on the child’s gender and age (Nauta et al.,novoPsych 2004).
